Application led April 11, 1914:. Y Serial No. 831,253.

To all whom it may concern.' K I Be it known that l, CHARLES VNELsoN, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented a certain new and useful Alcohol-Lamp, of which the following is a specification. y

The object I have in view is the production, in a lamp for burning alcohol or other spirits by means of a wick and more particularly to that form of lamp in which the size of the flame is regulated by a vertically movable sleeve which more or less masks the flame openings inthe wick tube, of improved means for supporting and securing in place the means for manipulating the masking sleeve, which will be cheaper, stronger and more durable than the devices now in use. rlhis and further objects will more fully appear from the following specifications and accompanying drawings considered together or separately.

In the drawings, Figure l is a plan view of my improved lamp; Fig. 2 is a transverse section ofthe same taken on the line 2, 2 of Fig. l; Fig. 3 is a detail view on an enlarged scale, of the spindle and sleeve; Fig. 4 is a section on the line at, l of Fig. 3; Fig. 5 is a sectional view of a modification; and Fig. 6 is a detail view showing the manner of securing the bearing to the font.

ln all of the above views, like parts are represented by similar reference characters.

The lamp, in the embodiment of the invention, chosen for illustration, embodies the usual font l, which carries a wick tube 2, a flame controlling sleeve 3 and a spindle 4. The wick tube is provided with the usual wick 5, liame openings 6 and gas outlets 7 and it may be covered by the usual cap 8.

he controlling sleeve 3 is provided with a vertical series of slots 9 which are engaged by a pinion l0 on the inner end of the spindle, whereby the sleeve may be raised and lowered by the rotation of the spindle. The spindle is provided with a finger piece by means of which it may be manipulated.

The spindle is carried in a tube or bearing ll which pierces the side of the font top and extends inward toward the center of the font to thereby offer a long bearing for the spindle. T he top of the font is stamped or otherwise forced up and into a shape corresponding to that of the outside of the tube ll as shown at l2, and the projection or forced up portion tfube may be passed ont. The tube is wise 'permanently the cavity formed is perforated so that the soldered, brazed or othersecured to the inside of by the. projection l2, as

at 13, whereby a much stronger construction is secured than if ent and the tube is soldered in a more or less the projection is not presin a perforation vertical part of the top,

and the part to which it is soldered is no greater than the thickness of the stock ofwhich the font is formed, as is the usual construction.

The pinion 10 is of a than the diametei making it possible to insert diameter no greater of the spindle therefore the spindle and pinion through the ytube from the outside and, when in position, the pinion will engage the slots 9 alinement.

and hold the sleeve 3 in The manner of securing the spindle in the sleeve is as follows: The spindle is circumferential groove 13,

with a 14: is placed over and its end l5 is over so as to engage the groove.

provided a thiinble the outer end of the tube spun or otherwise turned The tube l1 near its outer end is provided with a perforation 16 and the thimble lil is secured to the tube by means of a small indentation which enters the perforation 1.6. This indentation may be made by a punch or a like instrument. The ble will securely intuined end of the thimliold the spindlev against longitudinal movement and the frictional engagement of the spindle with the tube will be suflicient to retain the sleeve 3 in any desired position.

Should it become necessary at any time to remove the when the spindle thiinble, it may be readily cut or filed apart and removed from the sleeve ll, can be withdrawn, and

when the parts are reassembled a new thimble can be secured pense.

in place at very slight eX- ln the modification shown in Fig. 5, the

end 17 of the tube groove 13.

is produced.

1n accordance patent statutes,

1l is turned over into the ln this construction the thimble is dispensed with and a cheaper device with the provisions of the l have ple of my invention,

described the princitogether with the apparatus which l now consider to represent the best embodiment thereof it understood tha but l desire to have t the apparatus shown is into the interior of thev merely illustrative and that the invention may be carrried out in other Ways.

aving now described my invention, What I claim as ne and desire to secure by Letters Patent, is:

1. A lamp having a controlling shaft or spindle, a groove in the shaft or spindle, a sleeve surrounding the shaft and having its end turned into the groove to prevent longitudinal movement of theshaft.

'2. A lamp having' a controlling shaftor spindle, a groove in the shaft, a the shaft, a thimble on the bearing having its end projecting into and engaging the groove to the shaft. p

3. A lamp having a controlling shaft or spindle, a groove in the shaft, a bearing for the shaft, a thimble on the bearing, a lip on.

' Copies` of this patent may be obtained for bearing for prevent 'longitudinal movement of' the thimble for engagement With the groove, a perforation in the bearing, and an indentation in the thimble for engagement With thel perforation.

4L. A ling shaft, a peripheral groove in the'shaft, a bearing-for the shaft, a cavity in the font for receiving the bearing, means for seour' ing the bearingv to the Wall of the cavity, the end of the bearing being turned over into the groove to prevent longitudinal move-V ment of the shaft.

This Vspecification signed Y and witnessed this 3rd day of April, 1914. Y. K CHARLES NELSON.
